Tidybook: Duplicate Contacts

Merge duplicate contacts and fix incomplete entries, unlimited and free. No account, no ads. 100% on-device — your contacts never leave your phone.

Tidybook finds duplicate and incomplete contacts on-device and helps you clean them up in a few taps — no account, no ads, no limit on how much you can merge.

YOUR CONTACTS NEVER LEAVE YOUR PHONE Every scan runs locally using Apple's own Contacts framework. No account, no upload, no server. Nothing is ever sent anywhere.

WHAT TIDYBOOK FINDS • Duplicate Contacts — grouped automatically by matching name or phone number, with the most complete entry suggested as the keeper • Incomplete Contacts — entries missing a name or phone number, so your address book stays usable • All Contacts — browse and manage your entire contact list in one place

MERGE WITH CONFIDENCE Pick exactly which contacts to combine — unselected contacts in a group are never touched. Back up everything involved as a vCard file before merging, right from the review screen, so you always have a copy to fall back on.

TAP TO VIEW, SELECT TO ACT Tap any contact to open its full native contact card — the same detail screen the built-in Contacts app uses. Selection is separate from viewing, so browsing your list never risks an accidental change.

UNLIMITED AND FREE No daily merge limit, no subscription, no paywall on the features that matter. Many contact-cleaner apps charge to unlock the one thing you opened them for — Tidybook doesn't.
